Image-Nodes

Image Nodes are the indivisible building blocks (like atoms) from which textures are made.  They perform a wide variety of simple and straightforward image manipulation tasks, such as generating a gradient or blurring an image.  Yet despite their apparent simplicity, just about any material can be simulated by stringing together the right combination of Image Nodes.

 

Image Nodes will be most useful to experienced Genetica users.  New users should check out the Advanced Nodes.

 

Image Nodes fall into several categories, as shown in the following table.

 

 

Category

Description

3D

3D nodes use a height map to create various three-dimensional effects.

Blur

These nodes soften their input by blending nearby pixels together.

Color

Nodes that influence the color of their input.

Combine

These nodes combine multiple inputs into a single image.

Effect Map

These nodes don't affect the texture itself, but rather allow you to create and manipulate additional channels that can be used by 3D applications (as bump or specular maps, for example).

Environment

Nodes that create and manipulate environment maps (HDRI spherical panoramas).

Filter

Nodes in this category take a single input which they alter in some way.

Generate

These nodes create basic patterns from scratch, and therefore often serve as the starting points of your textures.

Group

These nodes allow you to organize the nodes comprising your textures into units that are easy to understand, edit, and reuse.

Transform

Nodes that remap the pixels of their input to new positions.
